Frequently Asked Questions
Q: What equipment does the 5050755-06 contactor fit?
A: The 5050755-06 is a 24VDC contactor rated for 300A nominal current, designed for electric lift trucks using GE EV100 motor controllers. It fits select Yale models, particularly those equipped with Yale 505075524 or Yale YT505075508 electrical systems. Verify your equipment model and control voltage before ordering.
Q: What are the cross-reference part numbers for the 5050755-06?
A: Cross-reference equivalents include Yale 505075524, Yale YT505075508, and Yale 505075508. The OEM part number is 505075524. If you have an older Yale truck or supplier documentation, these alternative numbers can help verify you are ordering the correct unit.
Q: What is the current rating of the 5050755-06 contactor?
A: The 5050755-06 is rated for 300 amps nominal current at 24VDC. This is the maximum continuous current the contactor is designed to handle in a 24-volt DC circuit. Do not exceed this rating to avoid premature contact failure or thermal damage.
Q: What voltage does the 5050755-06 require?
A: The 5050755-06 is a 24VDC contactor. It is designed for 24-volt direct current control circuits only. It cannot be used on 36-volt or 48-volt systems without damage to the coil and control electronics.
Q: Is the 5050755-06 a single-pole or multi-pole contactor?
A: The 5050755-06 is configured as a single-pole contactor. This means it switches one main power line. Single-pole designs are typical for lift truck main contactor applications where one high-current circuit needs to be opened or closed by a 24VDC coil signal.
